How will an external Hard drive designed for the macbook Pro work with my White Macbook?  My  white macbook has a Firewire 400 and the G-Tech HD has a 800 to 400 compatible cable for the firewire.

I am asking this because I want the G-Tech Hard drive  says that it is designed for the macbook pro.  Yet, I want to back up faster with by using my firewire 400 which is not an option on the one designed for the white macbook that does not have a firewire (only a USB port.)  The G-Tech Hard drive comes with the 800 to 400 compatible cable and has 5400 RPM with 750 GB.  Also, I've heard that laptops with low battery (mine all the time)  won't have the power for a bus powered Hard drive (as in no ac plug in adaptor.)  Can I just plug in my laptop?  Any one know the answers from experience with this hard drive?

As far as I know, if a harddrive works with a Macpro, it should work with the Macbook: if your Macbook is low on power, plug in the AC adapter
If your Macbook has a firewire port, then it should be fine. BUt i would do somemore research first.

  • Can I use Time Capsule 1TB as an external hard drive tos tore my music library(but with cable connection,not WI-FI)

    Can I use my Time Capsule 1TB as an external hard drive to store my music library but with a cable connection(Ethernet or USB) and not Wi-Fi.

    Yes, with the following warnings.
    1. A 1TB TC is a Gen3 or earlier and can die at a moments notice.. So backup is essential.
    2. A Gen1 or 2 is slow.. even over ethernet they were processor bound and so transfer speeds are not great.. a USB2 plugged into the computer will be faster. Gen3 is about 50% better as the processor was upgraded by 50% speed.
    3. TC has no built in backup.. TM cannot backup network drives.
    4. TC is designed to spin up slowly and spin down quickly.. you will have issues with itunes constantly losing the library.
    5. You cannot use USB to the TC.. it is a network drive. If you want to use USB directly on the computer buy a USB drive.. but buy as fast a drive as your Mac supports.. Thunderbolt>USB3>FW800>USB2
    USB3 is cheap and very good.. but the port is only from 2012 so check your Mac specs.
    Thunderbolt whilst being super fantastic and around since 2011, has a bank account clearing price although there are Thunderbolt to esata converters.. for around $160. esata falls between usb3 and fw800.
    FW800 from WD is no better than USB2 but other brands it can be twice the speed of usb2.
    USB2 is the worst. But still faster than a TC.

  • Will my external hard drive be recognized on the Windows side of my Mac?

    I have a 2009 white Macbook 13-inch running Leopard and fairly recently used Boot Camp to install Windows 7.  Unfortunately I made the Windows side too small and I am now considering using an external hard drive to download all of my files I need for work.  I have a few questions...
    1) Is this a possible solution to my problem of no space on my Windows hard drive? and
    2) I read something about my computer not having HFS read support since I didn't upgrade to Snow Leopard or install the Bootcamp driver upgrades (because it is my understanding they require SL).  Will my external hard drive even be recognized by Windows? If not, can I upgrade to SL now and install the Boot Camp drivers before I try to use my external hard drive?
    I just really want to do things right this time, since I'm already screwed with the partition size (there is NO WAY I am restoring the partition and reinstalling Windows 7) and I had a lot of hassles with Windows software when I first attempted Boot Camp.  Any help would be great! Thank you very much.

    Hey there Natasha1608,
    It sounds like you need to transfer your library that is on your phone to your computer, and point iTunes to your other iTunes library. For the first, you can transfer your iTunes Store purchases to your library with the following article:
    iTunes Store: Transfer purchases from your iOS device or iPod to a computer
    http://support.apple.com/kb/ht1848
    Keep this in mind from the above article:
    This feature works only for audio, video, and apps that you purchased from the iTunes Store. Any items that you imported from audio CDs or acquired from other sources won't copy from your device to the iTunes library. However, copies of all PDFs and books from your device's iBooks app will transfer to the computer, regardless of whether they were purchased from the iBooks Store. Learn more about transferring media to your iTunes library.
    To point iTunes to another library, use this article:

    How to decrypt external hard drive on lion filevault

    To do this, follow these steps:
    1. Open the OS X Terminal utility and run the following command:
    diskutil cs list
    The output of this command will look like a hierarchical tree. Locate the long alphanumeric code next to the words "Logical Volume Group" (this code is called a "UUID"), and copy this code to the clipboard by highlighting it and then pressing Command-C.
    2. Run the following command to destroy the logical volume group, replacing "UUID" with the alphanumeric string from the first command.
    diskutil cs delete UUID
    When done this will clear the volume and allow it to be formatted and otherwise customized. See the following screenshot for what this should look like (the two commands are underlined in blue:

    I want to take files from my PC (using a Seagate external hard drive) then plug this Seagate External hard drive into my Mac Book Pro and move the files from the Seagate External Hard drive onto my Time Capsule. I do not want to put these files on my Mac. How do I do this? Where do I put these files on my Time Capsule? Will it affect the functioning of my Time Capsule?

    Mixing files with data is not always great idea.
    See info here.
    Q3 http://pondini.org/TM/Time_Capsule.html
    Why not just connect the PC directly to the TC by ethernet and copy the files over?
    It is hugely faster and much less mucking around.
    In windows load the airport utility for windows.. if you have not already as this will help you access the drive.

  • Can't connect my external hard drive to my Mac Book Pro. Any thoughts?

    I have a 2.0 TB WD Mybookessential as an external hard drive to my Mac Book Pro and I'm getting a "The disk you inserted was not readable by this computer" message every time I try to remount it. Any thoughts?

    Thanks for the suggestion, Cattus, it is in fact a formatted disk with a lot of valuable data, so I do not want to reformat the disk.

  • What type and how many gigabyte external hard drive do I get for my iMac?

    What brand and what features and how many gigabytes do I need in an external hard drive for my new imac?

    I am sure if I spent the time reading those pages, I would lose more time than I would save with a Firewire drive if I ever had to do a complete restore. If you ever have to do a complete restore, just run it overnight. Do like I do, save your money, maybe buy some Apple stock, and you will make more than enough to compensate yourself for the extra time it might take.
    The only time you might need extra drive speed is for the operating system, or if you do a lot of heavy graphics and video work, or do a lot of work on a disk-based database. (If speed is an issue with a database, consider using memory-based software instead.) Backup is not on that list, unless having the computer up and running is so critical that you should be using a RAID backup system instead. For the vast majority of computer users, speed will not be an issue. After all, many people backup to Time Capsules over WiFi, and that is slower than USB2.
    When it comes to backup, people should be speedy about getting a backup drive. If the extra cost of Firewire causes a delay doing that, it could easily cost more time and trouble than the extra speed will ever save them.

  • My MacBook Air is running out of storage. Will an external hard drive work for me?

    Good afternoon, Apple support forums! I recently made a BootCamp partition, and now my MacBook Air is running out of storage (about 13 GB left), and I realize that I cannot expand the storage on my Macbook Air without some DIY technical work. I looked into alternatives and came onto external hard drives (I'm looking at the LaCie Porsche Design P'9223 USB 3.0 Mobile Hard Drive - 2 TB, but this question is for external hard drives in general). I was wondering, just in case, if I could use it not for backup (as I already have an Apple AirPort Time Capsule) but as added on storage for my Mac. Also, would I have to keep the external hard drive plugged into my Mac 24/7 to have access to the files stored on it? Thanks in advance for any help!!

    1. Yes, you can.
    2. You only need to have it plugged in when you're accessing data on it.

  • How to use external hard drive

    I purchsed my mac mini four years ago.  It came with an external hard drive.  I have never used it and don't know how or what i am doing!  But now that i have movies and pictures on my computer i want to make sure i have them backed up.  How do i work this thing?

    Hi, Alan.
    The Ext drive should have either a firewire or usb cable,and a power supply.
    The sockets on the mac mini for these 2 interfaces are different, so the cable will only fit into one.
    Make sure the plug is right way round and don't try and force it into a socket.
    Do this before you turn on the mac mini and power up the ext drive.
    Boot your mac, open applications, select utilities and then Disk Utility.
    If everything's working and connected you should see the ext drive listed on the left as the second entry.
    Click on it and DU will give you size, file system type, etc. If it came with your mac I suspect it will already be formatted.
    It should also appear on your desktop as the next icon under th Mac HD one.
    You can either use time machine to backup everything on the Mac Hd drive automatically, or simply drag and drop the folders you want to keep onto the new drive. It's easier if you open the drive's folder to do this.
    Hope this helps,
    regards,

  • How does an external hard drive compliment Time Capsule?

    Hi, I am relatively new to iMac and time capsule. I am a novice computer and Mac user so things have to be simple. I have been reading a number of threads in the forums gleaning as much information as I can. Any thoughts or suggestions would be greatly appreciated.
    My iMac is running OS 10.6.4 with a 313 GB HD and my time capsule is 500 GB. I purchased my first iMac 2 years ago. Shortly thereafter I decided that I needed to be backing up files that I have been creating and building especially my photos and music files so I purchased a time capsule which I have been using as an external hard drive not as a wireless router. It is hard wired to my Mac. I use another wireless network. I have used Time Machine a few times and it has worked well for me. So far this simple set up has met my needs.
    Just recently I got two error messages, one that "Your startup disk is full." and "The disk containing your iPhoto library is running low on space.
    While I was exploring my memory capacities and possible ways of freeing up space on my computer my Time Capsule croaked. Apparently all hardware has an expiry date. It has since been replaced under an extended warranty and the new one reinstalled. I have done a complete back of my hard drive and deleted some useless stuff on my computer's hard drive to create 17 free GB. I am pondering what further steps I should take to safeguard my data. I hopefully will be building a much more extensive photo library both in iPhoto and Aperture. I wonder whether I should be looking at an additional external hard drive which seems to be the easiest thing to do. My Time Capsule (500 GB) is not quite twice the size of my computer's hard drive. Maybe it is too soon to invest in an external hard drive seeing that it may have a shot life span such as my first Time Capsule did.
    Does Time Machine only work with Time Capsule or will it work with other external hard drives? The folks at my Apple store tell me that Time Capsule can be used just to store data but I have heard otherwise in the forums. How would an additional external hard drive will work with Time Capsule? What is the difference is between USB and firewire? Is it possible to open files stored on the Time Capsule to see exactly what they are?
    I do realize that Time Capsule only backs up new files and any changes so I wonder how long I can continue with this arrangement.

    Yes, Time Machine works with external HDs. That's how most folks back up. Connecting directly via USB or FireWire is much faster then Ethernet, but you're right -- all disk drives fail, sooner or later.
    The folks at my Apple store tell me that Time Capsule can be used just to store data but I have heard otherwise in the forums.
    It can be used for Time Machine backups and other things, but trying to use the same one for both presents problems, because of the way Time Machine works (filling-up all the available space before deleting the oldest backups) and the fact that you can't partition a Time Capsule's internal HD to separate your backups from the other data. Plus, you can't back up the other data.
    How would an additional external hard drive will work with Time Capsule?
    It won't extend the TC's internal HD -- backups can't "span" the two. In your setup, you'd be much better off connecting an external HD directly to your iMac. The advantage of a TC is, since it includes a wireless router, you can use it to make a wireless network and do backups wirelessly. That's what a lot of laptop owners do.
    What is the difference is between USB and firewire?
    FireWire is faster and more reliable for large amounts of data transfer. It also requires less use of your Mac's CPU, since the FireWire chipset does some of the work that your CPU has to do with USB.
    Is it possible to open files stored on the Time Capsule to see exactly what they are?
    Yes. Files you put there (other than Time Machine backups) are just like files on any other disk.
    I do realize that Time Capsule only backs up new files and any changes so I wonder how long I can continue with this arrangement.
    Yes, that's a concern. It varies greatly depending on how you use your Mac, but our general "rule of thumb" is that it needs 2-3 times the size of the data it's backing-up.
    There's another consideration: Time Machine can back up FROM your internal HD and external HDs that are directly connected via USB or FireWire (if they're formatted for a Mac), but it cannot back up from any network drive, including a TC's internal HD or a USB drive connected to it. So if you move some data from your internal HD to an external HD connected to the TC, you'll need some other way to back it up.
    Forgive me, but I'm not sure why you have a Time Capsule in your setup, if I understand it correctly. You have one iMac, no laptops or other computers, and you use a different router for your network, right?
    Your best bet may be to get one external HD for the "overflow" of things you don't have room for on your iMac's internal HD, and another, much larger one, for Time Machine backups of both.
    I'll press my luck here and also suggest yet another external HD, perhaps a portable, for "secondary" backups. With a portable, you can take it to a secure off-site location, such as your safe deposit box, workplace, relative's house, etc., and also be protected against fire, flood, theft, direct lightning strike on your power lines, etc. See #27 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] for more.
